<p><em>VLFeat C library contains implementations of common computer vision algorithms, with a special focus on visual features for matching image regions. Applications include structure from motion and object and category detection and recognition.</em></p>
<p><em>We strive to make the library free of clutter, portable (VLFeat is largely C-89 compatible), and self- documented. Different parts of the library are weakly interdependent, simplifying understanding and extraction of code.</em></p>
